🚨17-year-old Samuel Davis went to the Classic Mart & 420 Shop in San Antonio around 1 a.m. on Friday and tried to buy a 99-cent tobacco product. The store clerk refused to sell it to him because Davis was underage. The refusal led to an argument between the two inside the store. During the confrontation, Davis allegedly pulled out a knife and stabbed the store clerk multiple times. After the attack, Davis ran from the scene. When police arrived, they found the store clerk suffering from several stab wounds. He died at the scene from his injuries. Investigators reviewed store surveillance footage, which reportedly captured the incident, and a witness later identified Davis from a photo lineup. Police also spoke with a coworker who said Davis was a regular customer who often caused problems, acted aggressively, and was known to steal from the store. After a nearby standoff connected to the investigation, Davis was taken into custody and charged with murder. His bond was set at $500,000.
